Title: HASHING & DOUBLE ENCRYPTION TECHNIQUE FOR INFORMATION STORAGE IN CLOUD
Abstract: —Information storage in the cloud is very popular in recent days. The Cloud platform provides various services to its users and one of the important zones of service is the security of the information stored. This project proposes an enhanced approach of a complex Hybrid encryption system involving a Symmetric and an Asymmetric key encryption technique to secure the information on the cloud platform from potential attacks like encryption failure, man-in-middle attack and Insider attack etc along with a hashing technique for the key. The proposed hybrid encryption system involves a newly designed Symmetric key technique "Dehex Algorithm" which encrypts the information with a random key generated from the input size. The Dehex algorithm is followed by the ECC algorithm which is an Asymmetric encryption method. The output formed will be double encrypted information, which then reaches the cloud storage. The keys used for encryption need to be securely stored and so the keys are subjected to the SHA hashing algorithm. Hence this new approach can be one of the ways which can be used for securing information stored in the cloud.
